With the newest model of Dell laptop (Precision 7730) we have been having a bear of a time getting provisioning working, in part because the 32 bit Dell NIC drivers do not work if we use the legacy PXE boot option (which Dell has been zero help in). To get around this, we are UEFI booting off a thumbdrive that has the boot.wim on it. This works great, until the computer reboots, planning to go into Windows. At this point, there is no Windows Boot manager, and we have no way to boot into the Windows installation we just put on the machine. It seems the problem is because the provisioning job is creating an MBR instead of a GPT. We are using the automatic "create partition" action, which says it will use GPT if it sees we are in UEFI, but it only ever uses MBR instead.
My question is, is there a way to force the job to use GPT instead of MBR? If not, how do manually set up the GPT configuration?
Alternatively, if anyone knows what can use for a NIC driver to get legacy boot to work on these Dell Precision 7730's, I would be happy with that as well (legacy boot works fine on our other Dell laptops and desktops). We are using the latest 32bit Dell WinPE driver pack.
Thanks!
